We talked about it recently in this thread GE Switch & Outlet Failures
Apparently some capacitor goes bad (c7 I think?) and the issue usually is found after power is restored after an outage. I’ve just had two fail recently after power outages. The newer switches don’t seem to have this problem.
Jasco has extended warranties to 5 years. They sent me a replacement for free after contacting their toll free number. It’s worth trying to contact them.
Some report taking the switch apart and replacing the faulty capacitor which involves soldering it out, but that seems more trouble then its worth.
Short of replacing the switch or capacitor though, there is no other way to fix it.
